Agreed on the directions, it might appear to be piece of cake, but the "practically for free" part hides the hard bit: realism. Try simulating flight-search data with source, destination, flight numbers, routes, schedules , try a diff it against a real corpus. Even frontier models produce data that looks right at first sight, but breaks on joint distributions (a flight number that never flies that route, layovers that violate minimum connect times). last mile is the daunting task.
for what joy? and its posted on X , which is largely AI developed , ironical.. sorry . too late to that now .. we are well past that stage. and who will bell the cat .. everyone is an model developer, in some form or other.. and how much of ur post would reach this world fast filling with mass population working on ai projects ?
